Specification of Letters Patent.

Patented Dec. 18. 1906.

Application filed Dcccmhcr 28, 1906. Smal No. 293.600.

To all whom. t may concern;

Be it known that I, Janus ll. Sumo, a citizen of the United States, andn. resident of the city of Chicago, in the county of (ook and State ofIllinois, have invented cortnin new and use ul lm irovenn-nrs in Hoists;and I do hereby declare that tho following is a full, clear, and exactdoscriptimi of tho same, reference icing had to tho noomnpnn w ingdrawings, and to the letters of roforonco marked thereon, which form apart of this specification.

[his invention relates to improYonn-nls in hoists, and is shown moreparticularly as a hoist such as used in well-drilling, though useful forany re uired.

n drilling wells whcro considerable weight must be sup )ortcd upon thehoists and moved but a short distance at a (hoo es, for instance, whenloworing tools into or hoisting tools from a well-it has herotoforc boonnecessary to stop the motor or engine as ouch Section is adt ed to ortaken from the rod or it, is necessary to provide sonic type of shiftinmechanism or power il'tlllrilllhtiiifl) dcrior W ereby the engine ormotor can be disconnested from the drum during tho intervals betweenhoisting or lowering. Various tvpos of transmission devices have beentricd for the purpose, though none of the same hnvc proved entirelysatisfactory, owing to the necessity of having the movements of the toolat all times under absolute control,

The object of the invention is to provide a hoisting mechanism wherebyis maintained at all times oi ported thereon and whereby the articlesuprted upon the hoist may allowed to run mo and may be checked at anypoint in its descent. or when hoisting and supported without stopping orvaryi the speed of the engine or motor or the a justment of thetransmission mechanism.

It is also an object of the invention to afford a strong, simple, anddurable transmission of the class described not likely to 1; out oforder and capable of transmitting t a power of the motor with veryslight loss of war and whereby the control is positive lininstantaneous, tfereby insuring maximum efficiency.

The invention consists in the matters hereinoftcr described, and morefully pointed out and defined in the qipcnded claims.

In the drawings, igum l is a side elevapurpose for" which it hoist is te object suprfcct control scoured on snid drum-shaft hetwcon Lion,portly broken, of H, deviceembodying my invention. Fig. L is a ftH'Uview of the trnnsmission-com case. Fig. 3 is a section taken through theoonlrolling-wheel. Fig. 4 is an enlarged transvcise section of the splitadjustingwollnr. Figs. 5 and (i are contrul longitudinnl sectionsshowing it somewhat more compact construction in which one of the gearsis on the end of tho drum.

As shown in the drawings, A, A, and A indicate the rigid posts oruprights, )rovidcd with nlinod hcnringsu, (1,nnd oflnnd inwhichisjournulod the main (.lrum-shuft B. ltigidly the uprights or )USlS Aand A is a hoisting-drum, and rigidl y scoured upon said shaft B and hotween the uprights or posts A and A is the gmir-cnso I). Said gourn-useas shown is circular in firm, providing a rohitivcly broad outer(sylindric lure r! and is provided within tho sumo with a spider, asshown, consisting of four arms d, which are approximately atrangodninoty dogroos apart, and extend radinlly and in ulinomont with acorresponding boss (I on tho inner face of the pori ihcry d, and, n1;mourn. strong wchs of :nctal 0'' corn littl the inner pcriphory r! ofthe shell with the outer oxtromity of tho arms (1, thus affordingcompartments arranged equal distaut-cs apart and equal radial distancesfrom the shaft and in each of which is journalcd a beveled pinion I),having a dimneter greater than the width of said gear-case. As shown,said boss 4 and the arm (1 are drilled axially through tho shell toreceive a shaft J, as shown in Fig. 2, and on which said inion isjournalcd, and, as shown, a metal p ate d" is rigidly bolted to theshell to cover the end of the shaft and retain the same in place.

Journnlod to rotate freely on the shaft B between the car-case and the tA is a controlling-w ltPl E, which, as s own, comprises a spider havinga huh e and arms 0, on which is secured a rim 0, of any suitable ma-.terial, flanged on each side and enga which is a steel or othersuitable brake-liiiiig E, the cnds of which. on shown. are hinged to abroad arm E, pivotally engaged on the floor or frame hv moans of a shafte and which is ucluut by a lover e to draw said brake-band ti ht aboutthe conn. llingwheel or to re ease the same therefrom, as desired. Acollar r is secured on said Sllflft tween the hearing a and thecontrollingwhccl and against which the hub of said wheel bears.
